Dear WWF SupporterOn Saturday, 27 March, at 20:30 cities and towns across South Africa will be going dark to send a powerful message to leaders that the time to act on climate change is NOW. Please pledge your support for Earth Hour 2010 on www.wwf.org.za or SMS “EH2010” and your name to 34017 (R2/SMS). This year WWF challenges ordinary people to take the lead by pledging to reduce their carbon footprint. We have to show world leaders that we are serious and that we want them to deliver the climate deal our planet needs.Together we can make this happen.Remember to switch off your lights at 20:30, 27 March. We hope that you’ll be having fun in the dark. To see if there’s an Earth Hour event happening near you – click on the EVENTS button at the top of the Earth Hour homepage.
